.Application filed November 27, 1922. Serial No. 603,684,

i 'To all 'whom it may Cofnen.

Be it knoWn-thatI, HORACE HL MoRGANLa citizen of theUnitedStates of America, re-'- siding atl Detroit, in the county of Wayne and State of Michigan, have invented'cere tain new and useful Improvements in Convey'er-Chains, of which the -following is a speciiclation, reference being hadtherein to the accompanying drawings. i

The invention relates to conveyer chains and refers particularly to that type provided 'with a pusher dog for propelling an object such as a truck or the like which is supported upon the floor independently of the conveyer chain. VOne of the objects ofthe inventio'n is to provide a conveyer chain with knock-over pusher dogs which are so arranged that both the lupper or working and lower or return portions lof vthe conveyer 2Q chain with the pusher dogs will occupy but a` minimum space between the member of the truck'against which the force is'to be applied and the floor. Another object is toprovide a conveyer lchain with apusher dog pivotally 2i connected thereto between its sides to permit vthe minimum size of channel track which would accommodate a plain conveyer chain without any pusher dog attachment. vVVitlir these and other objects in view, the invention 3U resides in the. novel features of construction and combinations and arrangements of as more fully hereinafter set forth.

Ii thedrawings: l Figure 1 is a side, elevationv of'a conveyer, chain embodying my invention; v

Figure 2 is a cross sectional lelevation ithereof; Figure 3 is a top plan view'of 'a portion off the conveyer chain;

' 0 Figure 4 is aplan view of the pusher do Figures 5 and 6 lare respectively a vsi e elevation and planv view of a modified oonf struction of pusher dog y 1 j Figure 's a perspective view of a modl- 45. fied construction of conveyer chain with one of my pusher dogs attached.

YThe conveyer chain has the upper or working and the lower or return portions l and parts 2 respectively and passes around sprockets at links.

chain comprises the alternate links 5, which are formedof solid malleable castings and have the side members 6 and the barrels 7- with its pivot portion 11 connected to the .barrels 8 of these links. Each pusher dog has the transverse pusher head 12 'at one end which is adapted toengage the member of` the truck against which the force is -to be applied. Each pusher dog also has at the other endthe tail 1-3 which has a width'slightly less thanthe length of the barrel 7 and a weight sutiicient to rotate the dog about its pivot so that whenthe pusher vdog is located upon the `working portion 1 of the conveyer chain, its pusher head 12 is in position to engage the member of the truck against which the force is to be applied. The tail 13 preferably has in its lower side the recess 14 for tting over the barrel 7 of thechain link so that the pusher head can be raised to a greater extend above the wearing portion of the conveyer chain.

For the purpose of mum size of channel track which would ac 'Tommodate a plain conveyer chain without anypusher dog attachment, each pusher dog is pivoted to a chain link 5 intermediate its sides. In detail, the central portion ofthe permitting the mini-V barrel 8 of the chain link 5 to which a pusher dog is to be attached, is omitted so that the barrel 8 of thisl chain link comprises two lspaced stub barrels.

The space between these stub barrels is sufficient to receive the 'to receive the pivot pin 16 for connecting this end of the link 5 to the pair of adjacent links v l In the modified construction shown in Figures 5'and 6, the tail portion 17 of the pusher dog 18 has a width substantially the saine 'as that of the conveyer chain so that this pusher dog when located upon the upper or working portion ofthe conveyer chain rests '.upon'the upper surfaces of the chain As V'showin in Figure 7 the conveyer chain comprises alternate inner and outer pairs of 'pivotally connected links 19 and 20Vrespectively in which the inner pair of links aresepa'rated suiciently to receive the pivot portion 21 of the do 22 which is rotatably mounted upon the c ain joint pin 23 connecti'ng'I adjacent ends ofthe pairs of links. Wlth the above arrangement of conveyerchain and knock-over pusher dogs, it `Will be readily seen that both the Working and return portions of the conveyrvchain with their pusher dogs may require but the minimumA distance between the member of the object being pushed and the floor.y `Also, since the pusher dogs are pivotally connected to the conveyer chain intermediate its sides, theJ minimum size of channel tracks which would accommodate a plain conveyer chain Without any pusherydog attachment, is permissible. Still another advantage is secured by pivotally mounting the pusher dogs uponv the pivot pins of the conve-yer chain links.

What I claim as my invention is: y 1. The combination with' a conveyer chain having a series of pivotally connected links, yof a dog having a head, a tail, and an intermediate pivot portion, said ivot portion being connected to the chain y one of the pivots'connecting the links and said tail extending over an adjacent, pivot connecting the links. 2. The combination with a conveyer chain having one of .its links provided with sides and aligned spaced stub nbarrels,.of a dog upon lsaid chain having` a pivot portion located between said stub barrels and pivotally connected thereto and a second portion overlapping a link connected to the end of said first-mentioned link opposite to, said "stub barrels. l I

whereof I aiiix my signature.

In testimony HORACE H. MORGAN.
